PTA torch for outside surfacing of small-sized parts |
PP-9S PTA torch is designed for outside plasma transferred arc surfacing (the PTA-process) of small-sized parts.
PTA torch has vertical version in which all nipples for connection the feeding communications on the upper end are placed.
The PTA torch complete set includes two couples of
plasma and focusing nozzles of different dimensions.
Indeed, there are two torches in one. Necessary combination
of nozzles is selected according to required power and concentration
of plasma arc (see Table I.).
It is possible to deposit Fe-, Ni- and Co- based alloys
on working faces of different parts to protect them against
wear, corrosion etc. Pure argon (99,995% Ar) is used as
a working gas.
